Toyota Avalon

What year? If it's a '97-'99, it has has the same engine as the V6 Camry (1MZ-FE). In that case, TRD does offer a supercharger. Alternativley, you could go the custom turbo route like a select few here have or are in the process of doing.

my friend had a stock avalon and it was fast so the supercharger should well lets say go really fast :lol:

does he want to do just engine work or body nd intrior work as well???
